Request to fit vivo iQOO gaming mobile phone full screen

Hello, I'm a player from China's Minecraft International Edition Bedrock Edition. I want to fit the full screen of my device's water drop on the Bedrock Edition. Because there is no adaptation, there is a large black border on the left camera part of my device, which is particularly uncomfortable to play. I tried changing the aspect ratio of the third-party application in the settings, but it didn't work. I tried the latest stable version 1.13.x to the beta version 1.14, but none of them solved the problem.
My device: vivo iQOO (V1824BA)
Android version: 9.0
vivo customized version: Funtouch OS 9
Screen resolution: 2340 × 1080
Screen size: 6.41 inches
Processor: Qualcomm Snapdragon 855

My English is not very good, so I use Google Translate. Please understand if there is a syntax error. Thank you!
